You want WinZip on Amiga? get X-Arc............or WizARC, PERIOD!
WizARC is better, ut X-ARC looks like a WInZip because of its large icons. Also you can Use DiskMaster II you can add lha and unlha as one of the options on the menu like the copy and extract lha. this is actually the best way that I know of on The Amiga and it is super Duper easy!
